ANGUS J. DARRAGH, OF ALLEGHENY, PENNSYLVANIA.

LEATHER-STUFFING WHEEL.

SPECIFICATION forming part of Letters Batent No. 421,249 dated February11, 1890.

Application filed July 2'7, 1889. Serial No. 318,831. (No model.)

To aZl whom, it may concern.-

Be it known that I, ANGUS J. DARRAGH, a citizen of the United States,residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inLeather-Stuffing WVheels; and I do hereby declare the following to be afull, clear, and exact description of the invention, reference being hadto the accompanying drawings, which form part of this specification.

My invention has relation to wheels designed and adapted for use in theprocess of stuffing and improving leather; and it consists inthe novelconstruction and combination of parts, as hereinafter fully describedand claimed.

In the accompanying drawings, Figure 1 is a vertical transverse sectionof a stuffingwheel embodying my improvements. Fig.

, is an end View of the same.

A designates the stuffing-wheel, consisting of a cylindrical hollowchest. The walls and head of the wheels are double, the cylindricalportions being concentric and the heads parallel. The inner shell D isperforated at c for the passage or circulation of hot water, heated air,or steam from the end spaces F to the annular spaces G. The steam,water, or heated air enters the heating-spaces through the journals II Iof the wheels, which are made tubular, as shown, for the passage ofwater, steam, or heated air by branch pipes 71. i, the former being theinlet and the latter the outlet or exhaust. The course of the water,steam, or heated air is indicated by arrows,being first introduced. intothe spaces between the two heads S T on one side of the wheel, then byway of the perforations c in the inner cylindrical shell D to theannular space 0 around the latter, thence to the space between the headsS T in the opposite side, and finally out by way of the exhaustpipe 2'.

The stuffing=wheel may be constructed of wood, iron, or other suitablematerial; but I find itconvenient to build it in the general form of awooden cask. The inner and outer walls of the cylindrical body areformed of staves bound together with iron hoops.

In building the wheel both inner and outer heads are sunk into the innercylinder and hooped with galvanized-iron hoops. Wooden hoops of thethickness of the steam cylinder are then put on the ends of the innerstaves around the outer head. The outer staves are then put on and boundwith iron hoops. The door 11 is in one end of the wheel, as shown, andcloses an opening I, through which access is gained to the interior forfilling or emptying.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

In a leather-stuffing wheel, the combination, with the inner cylinder D,constituting the receptacle for the skins and provided with the doubleheads S T, of the outer concentric cylinder A, supported by and upon theinner cylinder, the said cylinders, with the heads S T, constituting ahollow or double walled chest, the inner cylinder being perforatedaround the space inclosed by its heads for the passage and circulationof the heatingfiuid, and being provided with hollow journals on oppositesides, through which pass steam or hot-air pipes for the entrance andexhaust of the steam or other heating-fluid, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this8th day of July, 1889.
